It is located slightly above 50 km. [28] According to measurements by the Magellan and Venus Express probes, the altitude from 52.5 to 54 km has a temperature between 293 K (20 °C) and 310 K (37 °C), and the altitude at 49.5 km above the surface is where the pressure becomes the same as Earth at sea level.
For example, Venus has an effective temperature of approximately 226 K (−47 °C; −53 °F), but a surface temperature of 740 K (467 °C; 872 °F). [ 13 ] [ 14 ] Similarly, Earth has an effective temperature of 255 K (−18 °C; −1 °F), [ 14 ] but a surface temperature of about 288 K (15 °C; 59 °F) [ 15 ] due to the greenhouse effect in ...
Baltis Vallis / ˈ b ɔː l t ɪ s ˈ v æ l ɪ s / is a sinuous channel on Venus ranging from 1–3 km (0.62–1.86 mi) wide and ~6,800 km (4,200 mi) long, slightly longer than the Nile and the longest known channel of any kind in the Solar System. It is thought the channel once held a river of lava.
The highest point on Venus, Maxwell Montes, is therefore the coolest point on Venus, with a temperature of about 655 K (380 °C; 715 °F) and an atmospheric pressure of about 4.5 MPa (45 bar). [ 131 ] [ 132 ] In 1995, the Magellan spacecraft imaged a highly reflective substance at the tops of the highest mountain peaks, a " Venus snow " that ...
Thursday's astronomical event will be best seen one to two hours after sunset before the trio sets in the western sky. Sunset on Thursday takes place at 5:40 p.m. EST in New York City, 5:33 p.m ...
At this height, the temperature is a manageable 75 °C (348 K; 167 °F). At 5 km (3.1 mi) higher, it is a temperate 27 °C (300 K; 81 °F) (see Atmosphere of Venus § Troposphere). The atmosphere also provides the various elements required for human life and agriculture: carbon, hydrogen, oxygen, nitrogen, and sulfur. [5]
